There are many implementations of DEVS Modeling and Simulation in various computer languages and software tools. Most of them focus on modeler-friendly approaches which mean a user should have knowledge of modeling and computer languages. In this paper, we introduce high and low level design methodology to help domain experts (who might not have an in-depth(More)
Web service technology is used to augment software reusability and composability providing XML-based message passing and operating system platform neutralization. Business Process Execution Language (BPEL) is commonly used to integrate web services called business processes, and implementations of BPEL vary according to venders. BPEL components have simple(More)
Interoperable DEVS modeling and simulation is desirable to enhance model composability and reusability with DEVS models and non-DEVS models in different languages and platforms. The barrier to such interoperability is that DEVS simulators implement the DEVS modeling formalism in diverse programming environments. Although the DEVS formalism specifies the(More)
DEVS Modeling and Simulation (M&S) has various implementations with various computer languages such as JAVA, C++, and C#. To enhance model reusability with different implementation, we need interoperable systems such as CORBA, HLA, and SOA, and an interoperable mechanism for simulation of heterogeneous DEVS models. As an infrastructure of an(More)
As the network uses, and especially the number of internet users, increases rapidly, an efficient system for managing large network traffic datasets becomes an important issue. There are several network traffic analysis tools such as tcpdump, Ethereal, and other applications. But, these tools have weaknesses: limited size of files, command line execution,(More)
This paper presents a cloud computing architecture for discrete event system modeling and simulation. Simulators with models used in the cloud computing are considered as web services which are accessed via web browser. This environment supports the simulation of homogeneous or heterogeneous models without much knowledge of discrete event modeling and(More)
